1.0 PRODUCT SUMMARY
1.1 Product summary
The MX 1x2 RF, a 19” 1U rack mounted 2×1 RF switch, is typically used for
simple switching or redundancy of the RF signal path. When one of the RF signal
inputs experiences a fault, it automatically switches to the other RF input signal,
ensuring the system’s continued operation.
1.2 Product features
• High frequency monitor resolution.
• Optional RS232 communicate port.
• Optional Integrated SNMP network management function.
• Automatic or manual switchover mode.
• Switch reference level can be set by front panel.
2.0 CONTROLS, INDICATORS, AND ALARMS

Shown with RF ports on front panel for display purposes
When the Switch Mode is selected as “Automatic State”, the input power on main
channel will typically be the one running at a higher RF level and will be the primary
output. If the main input is lower than the switch point power defined, and the input
power on subordinate channel is higher than the switch point power defined, then the
unit should switch the output from the secondary input
When the Switch Mode is selected as “Manual: Input 1 out; Input 2 out”, select the
desired channel output.
